KETTLE-FURNACE.

Specification of Letters Patent.

Patented Aug. 16, 1921.

Application filed June 1, 1920. Serial No. 385,796.

To all whom it may concern:

Be it known that I, OSCAR P. SANDERS, a citizen of the United States, residing at lVaco, in the county of McLennan and State of Texas, have invented certain new and use ful Improvements in Kettle-Furnaces, of which the following is a specification.

This invention has relation to certain new and useful improvements in furnaces and comprises a kettle furnace of simple construction and which embodies certain novel features of construction; the primary ob ject being to provide a kettle furnace the diameter of which can be regulated so that different kinds of fuel may be burnt.

It is also within the scope of the invention to provide an extremely simple, compact and inexpensive device of the character specified, which shall be serviceable, convenient and eflicient in its use.

With the foregoingand other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention has been illustrated in its preferred embodiments in the accompanying drawings, wherein similar reference characters have been employed to denote corresponding parts, and wherein:

Figure 1 is a side elevation of a furnace embodying my invention.

Fig. 2 is a sectional view.

Fig. 3' is a top View, and

Fig. 4 shows a modified form of a bracket.

In carrying out the aim of my invention I employ a sheet metal body 5, including the inner supporting brackets 6, each of which presents a smooth upper surface on which is held the circular rate plate 7.

Held to the member 5 is the door section 8, including the edge openings 9, 9, arranged in pairs and the vertlcally disposed flanges 10, 10, below which the door 11 reciprocates. This door section 8 is held by means of the bolts 4.

As shown the door is held by means of the outstanding metal lip portion 12, formed at the bottom of the door opening X, the door having the handle portion 13 at the upper end.

Held near the lower edge of the member 5, are the supporting legs 15. If desired the bracket as shown in Fig. 4 may be employed, this member including the securing car 16, the top portion 17, the bracket portion 18, continued in the stand portion. 19, the stand and ear portions having the bolt openings 3/ as shown. 7

The grate is in the form of a metal disk 20 having the openings 2. In one position of the member 5 the grate is snugly held in position while in the other adjusted position of the member there is a considerable amount of space around the grate, as when coal is burnt in which condition of the furnace the grate is shaken in opening the door, inserting a poker end into one of the openings and shaking the same so that the grate will slide on the bracket portion 18.

As shown in Fig. 2 the member 5 has the pipe opening 21 into which is flanged the collar 23, the crescent shaped member 24 being secured below the pipe opening said member having the centrally disposed drain opening 26. As shown in the drawings I provide a new deflector 24 arranged to deflect the products of combustion upward at the point of the escape into the pipe opening 21.

From the foregoing description, taken in connection with the accompanying drawings, the operation and advantages of my invention will be readily understood.

I have entered into a somewhat detailed description of the present and preferred embodiment of my invention in order to impart a definite understanding of the same. I do not desire, however, to be understood as restricting myself to the exact construction shown and described, as various changes or modifications may be made in the form, size, and minor details of construction without departing from the principles or sacrificing any of the advantages of this invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is:

A kettle furnace comprising a sheet metal member having bolt openings disposed in pairs near the vertical edge and a pipe openoutstanding lip to provide a rest for said ing, of a crescent shaped deflector held bedoor, a grate circular in outline, and bracklOW said opening, a door section having a ets held to said member to support said 10 suitable opening held to said member, bolts grate, all as and for the purpose set forth.

5 adjustably holding said door section, a door In testimony whereof I affix my signature.

slidably held to said section, the metal below said door opening being formed into an OSCAR PERDUE SANDERS.
